I think the speaker and minority leader do not want tp reveal the vote of congressmen who are voting against the majority of their districts. It has nothing to do with a 12 hour delay, or flying back to vote.
If you look at the county map of the US, it is “flyover country” money that will pay for the Big City impact.
Massie is correct...squishes like Ben Sasse of Nebraska won’t be able to hide his duplicity from his constituents.
